I want to convert a savage xl to a flux super crawler. Why the xl? I need ground clearance on all components. So im thinking 30 mph, full allu suspension on tank tracks, im making my own tracks, my main concern is, which motor esc will be best for 30 mph max, and super low crawler speed without overheating. And i would prefer brushless but not sure how they handle low rpms

I dont want to just crawl it, i want to build a rc that can run anywhere.

Please no input on if its.going to work, i just need someone that knows alot about motors and esc's.
